Opisthobranch of the Week Data
Atagema sp. 1 is considered to be very rare in Okinawan waters; I've never personally seen an example of this animal during many years of diving here and Atsushi mentions (pers. comm.) the featured animal is the only one he's seen. Atsushi found this attractive dorid beneath rock in the waters off Gahi Island in the Keramas.* I've also added a second page with an additional image of the above featured animal. Atsushi's images are used here with his kind permission.
There is a very similar animal in the new Gosliner book (Atagema sp. 7, p. 193, Gosliner, et al, 2015).
I've previously featured on these pages one other member of the genus, Atagema intecta, from the waters of Okinawa's main island.
* Keramas = the Kerama Islands Group, located 30 ~ 40 kilometers west of the Okinawa capitol, Naha.
